Abstract
An automatic quality control system for a machine which measures workpieces processed by the machine. An estimated value to be obtained from an unprocessed workpiece depending upon information obtained from previously processed workpieces is calculated and is compared with a predetermined control limit. An instruction signal is generated when the estimated value is beyond the control limit to indicate a need for adjustment of the machine.
